Abstract (en)
[origin: WO2005117446A1] The invention relates to a method, a device, and a computer programme product for calculating a motion vector from an interlaced video signal with interpolating a first pixel sample from a first set of pixels and a second set of pixels using a first motion vector, and interpolating a second pixel sample from the first set of pixels and a third set of pixels using a second motion vector. To improve motion estimation and de-interlacing, the invention provides interpolating pixels of the first set of pixels to calculate a third pixel sample as an average of at least two pixels within the first set of pixels, calculating a first relation between the first pixel sample and the third pixel sample, calculating a second relation between the second pixel sample and the third pixel sample, and selecting an output motion vector from a set of motion vectors by minimising the first and second relation using the set of motion vectors.
